Black Zinc Chromate 1 Litre
$44.00 Inc Gst
You receive 1 Litre bottle of Black Zinc chromate pre-mixed working solution. This is a 1 litre working solution, this is NOT mixed with water, this is a pre-mixed working solution. Black Zinc is a trivalent chromate conversion coating for zinc.
Black Zinc is an extremely popular chromate option given the desirable black finish it produces. It is used to produce a black chromate conversion coating on either zinc or cadmium electrodeposit by simple immersion. This process gives a final attractive glossy black finish with very good corrosion protection. Unlike the other three Jane Kits chromate options, the Black Zinc chromate is not a concentrate that requires mixing with water, it is in fact sold as a ready mixed working solution. The freshly zinc plated articles are immersed in the Black Zinc working solution for 30 to 90 seconds to produce a tough and very desirable attractive gloss black finish. Black Zinc treatment bath should be run at a temperature between 22 to 31 degrees Celsius.
For Black Zinc passivation, an additional final water dip is required. The makeup of the final water dip should include 30% JPK Aqualac. This process will eliminate iridescence and can be introduced across other chromates if desired. JPK Aqualac can be purchased separately and is found in the Chromate / Passivating category.
NOTE parts should be activated prior to chromating using Metex IT which is available for purchase in the Activators category.

The Jane Kits story began when John, a vintage motorbike restorer realised that it would be much more convenient and economical if he was able to plate his own parts in the home workshop. So John decided to source and create his own plating kit and hence Jane Kits was born. John went on to receive numerous awards for his meticulously restored bikes with parts plated using his ingenious new kit.
